EDGE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,883, dated. March5, 1889.

Serial No. 278,061. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN E. DRAKE, a citizen of the United States, and aresident of Quincy, in the county of Norfolk and State of Massachusetts,have invented new and useful Improvements in Edge-Setting Machines, ofwhich the following, taken in connection with the accompanyin drawings,is a specification.

This invention relates to improvements on the patent issued to PatrickMcLaughlin and myself December 6, 1887, No. $74,314:, for edgesettingmachines, and it is carried out as follows, reference being had to theaccompanying drawings, wherein Figure 1 represents a plan view of theinvention, and Fig. 2 represents a cross-section on the line A B shownin Fig. 3 represents a longitudinal section on the line C D shown inFig. 9.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

a is the head or frame oi the machine, provided with bearings a u, inwhich is journaled the driving-shaft h, havii'ig at one end secured toit the pulley h, to which a rotary i motion is imparted by means ofbelt-power, as usual.

The shaft 1) has between its hearings a crank or eccentric, h, to whichis pivoted the rear end of the connecting-rod c, the forward end ofwhich is pivoted to the block (7, that is guided between thelongitudinally grooved or inclined ways or cap-plates a a, secured in anadjustable manner to the frame or head a, or plates secured thereto,substantially as and for the purpose shown and described in theabove-mentioned Letters Patent. In this manner a forward and back motionis imparted to the block (I from the rotary drivin -shaft b and itsconnections to said block. To the block (I is secured in a suitablemanner, or cast in one piece with it, the tool-carrier e, that extendsto one side of the head a and at or about a right angle to the same, asshown in Figs. 1 and f and 9 represent the edge-settin g tools, one ofwhich is intended for setting the sole-edge around the toe and sides ofthe sole, and the other one for the purpose of setting the edge at theshank portions of the sole.

f and g represent, respectively, upwardly projecting shanks on saidedge-setting tools, which shanks are guided and longitudinally yieldingin cylindrical perforations in the hubs e e, that form a part of thetool-carrying arm 6, as shown.

The shanks f are automatically forced downward with a yielding pressureagainst the upward pressure on the shoe held by the operator by means ofsprings F G, the inner ends of which are suitably secured to thetoolcarrier 6, and having their outer free ends normally resting on theupper ends of the re spective hubs c and e", as shown.

Projections c on the lower ends of the perforated hubs e c prevent theedge-setting tools from turning around during the operation of themachine.

For the purpose of preventing the shanks f g from dropping out of theperforated hubs c c", I make on said shanks the respective grooves orslots f" 9, adapted to receive the spring-pressed pins f 9 that passthrough respective perforations inthe hubs c c", and I are attached toor form parts of the springs ff that are secured to the hubs c c", as 5shown in the drawings. 3y pulling said i springs outward in their freeends the toolshauks are released, and the tools may be removed forrepairs or otherwise whenever so desired.

In a machine of this kind having the tool carrier projecting to one sideof the reciproeating block an unequal strain is caused on thereciprocating block and its guides, and l to prevent this I extend thetool-carrier c in l l l the form of an arm, E, projecting to theopposite side of the machine, as shown in Figs. 1 and 2, said armtern'iinating as a foot or rest, E, adapted to be supported on and slideon the stationary bar or guide a", that is secured to or cast in onepiece with the frame of the machine, as shown in Figs. 1 and 2. i Iprefer to cast the part E in one piece with the tool-carrier 6; but, ifso desired, said arm E E may be secured to the carrier 6 or to the blockd to equal advantage withoutdeparting l from the essence of myinvention. By this construction. of the machine all unevenness ofpressure on the block and its guides will be obviated, and consequentlythe device may be operated with more precisionpvith less amount offrictional resistance, and to better eltect as compared with others notprovided with such extension and rest for it.

hat I Wish to secure by Letters Patent,

and claim, is-

The edge-setting machine, as described, consisting of the stationaryhead or frame a, the reciprocating block (1, mounted therein, and thetool-carrier e, secured to or forming a part of said block andprojecting to one side of
